mechanically operatingthe nuts upon bolts used in connection with the cover andmatriX of a retort press.

One object of my invention is to lessen the manual labor required in manipulating the machines now in use, and to increase. the output of the retort press by largely reducing the time consumed, in tightening. and loosening the nuts by hand, which I now accomplish by mechanical means.

A. further object is to provide a mechanism which will be strong and durable, and which will be simple in construction and easy of operation.

With these objects in view, my invention consists in a hydraulic pressure actuated mechanism characterized as above mentioned and in certain details of construction and arrangement of parts, all as will be hereinafter fully described and pointed out in the claims. 1 a f My invention will be readily understood by reference to the accompanying drawings, forming a part of this application, and in which I Figure 1 is a side elevation of my invention. Fig. 2 is an end elevation of the same. Fig. 3 is a horizontal section through the clay cylinder. Figs. 4 and 5 are atop plan and side elevation respectively of one of the nut operating levers. Figs. 6 and 7 vare a top plan and a vertical section respectively of one of the lower nuts. Fig. 8 is a side elevation of the lever operating bar. Fig. 9 is a. top plan view of one of the toplocking nuts. Fig. 10 1s a vertical section of the same. Figs. 11, 12 and 13 are detail VIEWS of modifications of parts of the machine.

In the drawings 1 is a clay cylinder of the ordinary kind, and is connected to'the frame or other stationary supporting portion of the press in any preferred manner, insuring the requisite stability. The clay cylinder 1 is provided With looking bolts 2 and 3.

apertures.

The matrix a which is of the usual kind, 1s pivoted at one end to the locking bolt 3, and-1s provided at its opposite end with a hook shaped portion which engages the looking. bolt 2, when the matrix is closed. The cover 5 is. also of usual construction and is mounted in the same manner as the matrix. .The cover is provided with a hook shaped portion similar'to the matrix, which engages the locking bolt 2. k p

The lockingbolt 2 is provided, at its upper endwith a screw threaded. portion (not shown) which is engaged bya nut 2% Said nut is split as shown in Figs. 9 and 10 and is provided with a bolt a and nut b by means of which the nut maybe clamped uponthe bolt2. This construction allows the nut to be adjustedto take up wear and also prevents the nut, from, turning. A, collar may be used instead of the nut but this would not permit adjustment. The lower end of the locking bolt Qisscrew threaded and is provided with the nut 2 having a lug 16. This lower nut 2* has afcone shaped bottom for a purpose which will be hereinafter described. An adjustable collar 2 is also provided upon the locking bolt 2."

The locking bolt 3 is provided at itsup per end with the nut 3*, similar to the" nut 2 This nut has thelug's 3? provided with aperturesand a pin 3 passes through said The pin 3 engages a slot in the statiomarywyertical bar 1. The nut 3 is thus held from turning. At the lower end of said locking bolt 3, another nut 3 havingalug 16 is-provided...

Secured to the clay cylinder 1 in any suitable manner are the'hydraulic cylinders 6 and 7. Thecylinder 6 being of greater diameter than the cylinder 7. The cylinder 6 isprovidedwitha piston 62 and the cylinder 7 wit-ha piston 7 i Abar having projectionsfland 10 is provided with'angular a-rms 8*,8 and the top ends of -these arms are connected by the bar 8 It isfto be noted that the bar 8 and thebar 8 in effect form a frame and the ramsjor ,pistonslof theihydraulic cylinders and 2 fit in the apertures 14 of the nut levers and their'lugs 16 engage the sockets 15 of the same. Screws 17 engaging the apertures 17 of thenut levers are providedto adjust the lugs 16 in the sockets 15. The levers 13 are provided at their outer ends with square headed bolts 18 as illustrated. When the parts of the mechanism are assembled in Operative relation, these square li'eads'18, occupy a position between the lugs 9,9 and 10, 1 0. The head'sof theseboltsaie e'nfg'ag'edby thel'ugs 9 and 10' of the bar 8 when the machine is in operation.

The lugs 10 area greater distance apart than the lug's 9 to" allow the full force of the pistons to strike one lever at a time, it having been found in practice that by strik in'g one lever at a time the full force of the operating ine'an's isutilitzed to start the nuts.

Hydraulic pressure from an accumulator or othe source; of supply is continuously adr'riittol to the cylinder 7 at Was indicated in Figs. 1 and 3.; The same hydraulic pressure undercontrol of a three-wayor equivalent valve (meshes 1'1) is admitted to cylinder 6 at 6 as indicated in the sainefigures, lVhen it is desired to raise the bolt 2' and the top nuts 2 and 2to' permit the cover and matriX to'be opened, the cylinder 6 is connected to the water supply and the pressure overcoining the constant pressure in cylinder 7 causes the rain? to move" the bar 8 with a rain 6", thereby ni'lovi'ng the bar 8 and projections 9 and 1 0 to the lef't, -a'n'd consequently the nut levers 13. Tlfh'is rnov'inent cau es the cone or the nut z tobe seated and a's' the auras gs as farther downward, the bolt 2 will rise; nd-[with it thenujtsfi' anus. Th not ,3? at the lower end pt the locking bolt?) Will be unscrewed slightly per? initting" the over and matrix to be turned thereon to open the clay cylinder; When the cover and matri'ii have be n moved to their closed position, water is exhausted from the port o or ar cylinder 6 and the constant pressure in cylinder 7 gives a reverse movement to the pistons, bar' frame and nut levers. I I p 1 The reason for employing cylinders of different diameters, is to siinplify the water connections of the cylinders andthe control of thesaiine, the water being at all times connectedto the smaller cylinder. By a conti ection'which will permit the water to flow from said smaller cylinder has th m-gar,

I thelarger piston will name are smal er pas:

ton to its original position, The crating off of the water supply froin the larger cylinder connecting said cylinder with an exhaust", permits the water to flow into the smaller cylinder, and, ,aslloi'lg as the exhaust from the larger cylinder is permitted, the pleas of the smaller" cylinder will be Moved to ieitect the exhaust of the larger cylinder and the movement of the connected parts,

as heretofore described.

It is not necessary that the lower end of nut 2 should be conical as all that is absolutelyneeded is that the nut when loosened, should quickly seat itself upon a stationary part that would prevent its farther descent ,and raise the bolt 2. Such a structure is shown in Fig. 13- in which the nut is shown 5 as terminating in a plane surface and hav- 5 ing arigid part immediately beneath it.

I Instead of having the nut raise the bolt 2 [I have also caused the same to be raised by iaweight as shown in Fig. 11. In this construction a lever 2 pivoted to a firm support Elias one end connected to the collar 2 or connected directly to the bolt by means such I as is show in Fig. 12-,- or in any preferred manner; To the opposite end of the lever is secured the" weight'fZ sufiiciently heavy to raise the bolt; In place of the Weight a strong spring 2, shown above the lever, may be -e1n p'l0ye'd. The raising of the bolt 2 and connected parts, it will be readily seen, is for the purpose of enabling the matrix its cover to be; easily returned to closed position beneath the parts that engage them and force them tightly in the position required before the operation of the piston in the clay cylinder".-

What I claim and desire to secure by Letters Patent 1. In a retort press, the combination with clay cylinder, of a matrix and cover pivotall-y mounted at one end on said clay cyljinder, bolts and nuts" forb'r'inging said parts closely together durin the operation of the press; power actuated mechanism and connecting means to loosen saidnuts, and means for raising the bolt to which the free ends of said mats-x and cover are secured.
